A Phase 3 Study of 131I-Metaiodobenzylguanidine (131I-MIBG) or Crizotinib Added to Intensive Therapy for Children With Newly Diagnosed High-Risk Neuroblastoma (NBL)

This partially randomized phase III trial studies iobenguane I-131 or crizotinib and standard therapy in treating younger patients with newly-diagnosed high-risk neuroblastoma or ganglioneuroblastoma. Radioactive drugs, such as iobenguane I-131, may carry radiation directly to tumor cells and not harm normal cells. Crizotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving iobenguane I-131 or crizotinib and standard therapy may work better in treating younger patients with neuroblastoma or ganglioneuroblastoma.

Primary Objectives:

I. To determine in the context of a randomized trial whether the event-free survival (EFS) of patients with newly diagnosed high-risk neuroblastoma (NBL) is improved with the addition of iobenguane I-131 (131I-MIBG) during induction, prior to tandem autologous stem cell transplantation (ASCT).

II. To determine whether the addition of crizotinib to intensive multimodality therapy for patients with high-risk NBL whose tumors harbor activating point mutations in or amplification of the ALK gene results in superior EFS compared to a contemporaneously treated cohort of patients whose tumors lack these ALK aberrations.
